Dual Neurostimulant Therapy May Optimize Acute Neurorecovery for Severe Traumatic Brain Injuries

Neurostimulants (NS) can be used to treat patients with a traumatic brain injury (TBI) with altered levels of consciousness. We sought to determine if amantadine alone (monotherapy) versus amantadine + methylphenidate (dual therapy) would correlate with better neurorecovery (NR) among acutely hospitalized patients with a severe TBI. We performed a retrospective review of adult patients admitted to our level I trauma center from 2016-2019 with a severe TBI. NR was calculated by dividing the difference between admission and discharge Glasgow Coma Scale (GCS) scores by 12. Resulting ratios were used to divide the cohort into two groups: excellent NR (1) and non–excellent NR (
